This sounds like something Reddit should implement on their end if it doesnt work. Discord tries to make an embed for most sites but sometimes they are lacking access to the information required to be able to make a successfull embed.

I just found out about Chromium WebView's and Electron BrowserView's (Electron specific). This is an even better reason for them to add frame embedding for all websites as this actually embeds the webpage on a different process so that security concern with iframes is no longer an issue.
